The Mustang was completely redesigned in 1974 with the fastbacks turning into hatchbacks, hardtops into notchbacks or coupes, and the convertible was gone. The two remaining models were smaller and lighter, back to the way it was originally designed back in 1964. It was renamed the Mustang II. Gone were the large engines of the years prior, but the gas crisis started. The consumer responded by purchasing more Mustangs than any other year outside of 1965, 1966, and 1967. A Ghia model upgrade was offered on the coupe which consisted of spoke-style wheel covers, a vinyl roof, deluxe color-keyed seat belts, remote-controlled door mirrors, a Super Sound package, shag carpeting, wood-tone door panel accents, a digital clock, and a super-soft vinyl or Westminster cloth seats. Ford used the 1970 acquired Ghia Italian design firm for these design choices. The hatchback could be ordered with the sportier Mach options. The most popular option was the Rallye package which included white lettered tires, extra engine cooling, a competition suspension, color keyed mirrors, styled steel wheels, dual exhaust, a digital clock and leather wrapped steering wheel.
